IDC header gender changer

[kuon]

I am looking for something very simple, but for some reason I could not find anything.

I have some boards with male 2.54 pin headers, like the GPIO header on the raspberry pi. And I'd like to stack them.

I am looking for female to female adapter, but I must be looking in the wrong category because after 1h I can't find anything.

To put it simply, the inverse of that:

I need 2 rows 40 pin 2.54mm, but it can be 2x 20pin if I can put them side by side.

Female/Female could be made with a small PCB and two SMT Female connectors.

Male/Female does exist for stacking boards as you will know

I thought of the small PCB, but I'll keep that of small resort.

one-of or production?

if one-of just solder two females together

Two, I soldered the connectors on the wrong side from my prototypes.

Your idea is brilliant, I'll just do that. I have low profile SMT headers lying around that should work.

Why not just use two female IDC connectors on an extremely short piece of ribbon cable? That’s infinitely less work than soldering two 40p connectors together, and should be mechanically more robust since it can flex.

So pins 1-2 on the first male connector map directly inline to pins 1-2 on the second?
